Detailed Product Overview

Dorman 599-742 is built for drivers and repair shops servicing GM full-size vans that use hydraulic brakes and the listed ABS configurations. It is a direct-fit control module solution for 2003-2007 Chevrolet Express and GMC Savana models, including Express 2500, Express 3500, Savana 2500, and Savana 3500 applications with the specified GVW and JL4 exclusions. This part cross-references OE numbers 1210232 and 13567136 for the same application.

By addressing the electronic pump relay weakness found in original equipment modules, this remanufactured unit helps restore ABS control function without changing the vehicle’s brake system layout. The Dorman 599-742 is a practical replacement when servicing GM van brake electronics on vehicles such as the Chevrolet Express 3500 and GMC Savana 3500.

What It Helps Solve

• ABS warning light caused by internal module failure
• Loss of anti-lock brake control from a faulty pump relay circuit
• Brake system communication issues related to the control module
• Intermittent ABS operation on hydraulic-brake GM vans
• Need for an OE-style remanufactured replacement for the original module

Installation Notes and Tips

Verify the vehicle’s year, model, GVW, brake type, and RPO code before ordering. This module uses a bolt-on attachment method and male connector/terminal layout, so connector match and mounting location should be confirmed against the original unit before installation. Professional diagnosis is recommended to isolate the ABS control module from wheel speed sensor, wiring, or hydraulic system faults.

Quality Assurance

Dorman remanufactures this OE FIX module with upgraded main pump transistors to improve durability over the original failure-prone design. Part number 599-742 is built as a direct replacement for the listed Chevrolet Express and GMC Savana applications.
